For two decades, documentarian Doug Block has supplemented his career as a filmmaker by shooting wedding videos. In 112 Weddings, he revisits some of his favorite couples to see how they've fared, and what wisdom they can impart about love and marriage. Block also follows two couples as they prepare for their weddings – first-timers Heather & Sam, and Janice & Alexander, a duo whose partnership ceremony he filmed 13 years ago, and who are now ready for “a different kind of commitment” after two children and a newfound desire to protect the family they have lovingly created.
